How AI Is Protecting Queenslands Iconic Cassowary Birds
In the lush landscapes of Far North Queensland, a battle is being waged to protect one of Australia's most iconic and endangered birds. The southern cassowary, a magnificent flightless bird crucial to the rainforest ecosystem, faces a constant threat from a very modern danger: traffic. But now, an equally modern solution is offering new hope.
The Challenge: A Deadly Collision Course
For the endangered southern cassowary, vehicle strikes are the number one cause of death. Last year alone, approximately two dozen of these majestic birds were killed in road collisions across Queensland. This alarming statistic prompted the Department of Transport and Main Roads (TMR) to explore innovative ways to prevent these tragic encounters.
How AI Steps in to Save the Day
A three-month trial on the Kennedy Highway at Kuranda deployed a sophisticated system to tackle the problem head-on. The "Large Animal Activated Roadside Monitoring and Alert System" uses a camera to constantly scan the roadside. When the system's artificial intelligence identifies a cassowary, it immediately triggers a large, flashing electronic sign to warn approaching drivers.
This high-tech alert system proved remarkably effective, boasting a 97 percent accuracy rate in identifying the birds. The result was a tangible impact on driver behavior and, most importantly, on cassowary safety.
The Promising Results
The trial yielded impressive results: fatal crashes involving cassowaries in the monitored area decreased by 31 percent. When the signs were activated, drivers reduced their speed by an average of 6.6 kilometres per hour.
Darryl Jones, TMR Far North District director, emphasized the importance of this speed reduction. "Hitting or swerving to miss a cassowary at speed can result in serious injury to both the driver and bird," he stated. "Slowing down by even a few kilometres per hour can substantially improve reaction time, braking distance and outcomes in the event of a crash."
Officials also noted that this technology has potential applications beyond cassowaries, suggesting it could be used to detect other animals or even monitor for children in school zones.
A Community's Hope for Expansion
The success of the trial has been warmly welcomed by local experts. Tully veterinarian Graham Lauridsen, who sees the tragic results of vehicle strikes firsthand, expressed his hope that the technology could be expanded. He suggested using existing data on cassowary crossings and hotspots to strategically deploy more systems.
"It will be really good to see how this technology, now we know it works, can be rolled out, especially into areas where there's hotspots of cassowary interactions," Dr. Lauridsen said.
An Ongoing Conversation
While the AI system is being hailed as a success, some local conservationists believe other factors may have contributed. Jax Bergersen from the Kuranda Conservation Community Nursery pointed out that speed limits on the Kennedy Highway were temporarily reduced from 80 kph to 60 kph for roadwork repairs during the trial period. "Once the speed limit was reduced to 60 [kph], we haven't had any deaths," she noted, suggesting that lower speed limits are a critical part of the solution.
Ms. Bergersen also stressed the cassowary's vital role as a "keystone species" for the rainforest. "Without the cassowary, a lot of that movement of big-seeded vegetation won't happen," she said, highlighting the urgency of protecting them.
As discussions continue about securing funding to roll the technology out more widely, it's clear that a combination of smart technology and sensible road management will be key to ensuring a safer future for Queensland's magnificent cassowaries.
